Poor Poor Fuel MPG
Asked by ddauer12 Mar 12, 2014 at 11:48 AM about the 2006 Mazda RX-8 6-speed
Question type: Maintenance & Repair
hey guys. i have a 2006 RX8 Shinka Edition. I have 81k on my car. Recently (5 days ago mazda sent me a brand new rotor motor and the dealership installed everything at no charge to me. Reason why is i was only getting 170 miles to a full tank of gas and they said the old motor failed the compression test. Now with the new motor im only getting 180 miles on my first tank and 170 miles on my second tank. Mind you i dont put my "foot down" on it. I run and shift gears around 4500-5000, i drive in 6 on the highway at 70/75. I will redline in 1st gear sometimes. Anybody have any ideas? its going back to the dealership to get looked at on friday

thanks for the advice. Ive been driving a stick for 15 years now. This tank im running super and im shifting at 3500/4000. im about 95 miles right above half a tank marker. I didnt buy it expecting great gas mpg but i thought better than 8/10 mpg. My last car i drove was a 2009 6 speed vette. i know big difference.
haha! You hear of RX8 having rear end issues??? I got a noise it comes and goes coming from the passenger rear side?
I will have the dealership check it out! thanks
Ha, ha, ha, dealership, poor guy.
Regular shifting rpm should be 4,000. Cruising should be 3,500 (3,000 minimum). Coils wires and plugs could be to blame for poor economy as well. I’m at about 137,000 miles on my R3 and was getting about 12mpg average. Replaced coils, wires and plugs and started using 87 octane fuel from 91 and now I’m averaging about 14mpg (I doubt the octane difference has anything to do with the mpg change though). Car runs better and keeping more money in my pocket is nice as well.
Because it doesn’t need anything more. (The fact that it’s an R3 doesn’t change anything)
